Kaito was sitting on the side as he watch the three if them absorb.
He released his aura allowing the essence to be naturally attracted towards him. Allowing the other three to absorb more essence.
He couldn't help but to think back, he do remember all of his past lives. He remember how he separates himself from his friends once he remembered who he is.
Once his half soul reawakens.
He remember searching for the other half on his own without asking anyone for help. As if he has no right.
But now that he is here with Astra and Hiro he felt like all of those times were nothing but passing times.
He couldn't contact them in the past and couldn't do anything on his own. Frustration building up as he knew his time is almost up.
He wanted to go back, he wanted to see them again but has no chance of doing so.
And in reality, his last two lifetimes. He had given up and lived his life like the person of the land he is.
